A Private Pricing Opinion — what your apartment at 243 East 77th Street would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
243 East 77th Street puts elevator access into a small prewar cooperative with a varied apartment mix. Conventional one-bedrooms share the building with larger garden duplexes and multi-level penthouse space. Private outdoor areas occur at both ends of the structure, including gardens, balconies and roof terraces.
The cooperative offering was accepted in July 1981 and became effective in January 1982, with Zefka Realty Inc. as sponsor. The original rehabilitation offering covered fourteen residences. Current city records carry thirteen.
Architecture and unit composition
The middle-floor apartments include one-bedroom layouts of approximately 800 to 900 square feet. Larger lower-level homes extend to roughly 1,300 square feet and can combine internal stairs with access to a private garden or balcony.
At the top of the building, penthouse space spans multiple levels with private terraces. The elevator reaches the entrance level of that configuration; stairs provide access to its other interior levels. A buyer seeking elevator access throughout a home therefore needs to distinguish the building's elevator service from circulation inside the apartment.
The range in floor plans is substantial for a cooperative this small. A conventional one-bedroom and a multi-level home involve different usable-area calculations, outdoor-space responsibilities and routes between rooms.
Building operations
The cooperative occupies a single tax lot and provides common laundry and intercom entry. Class 2 applies without assessment-growth caps, and no tax abatement is recorded. Its existing floor-area ratio exceeds the residential allowance under current R8B zoning.
The building's limited apartment count means common expenses are allocated across a small group of shareholders. The proprietary lease and share schedule determine how those charges fall on homes of different sizes, including the larger garden and penthouse configurations.
Policy framework
A seller-paid flip tax of 1.5% has been stated — confirm the current rate and calculation with the managing agent.
Pets are considered case by case; pieds-à-terre and in-unit washer/dryers are allowed — confirm with the managing agent. Apartment alterations remain subject to the cooperative's approval requirements.

Local Law 97
This building is below the 25,000 sq ft threshold at which LL97 limits apply to a building on its own. It is still covered if it shares a tax lot or condominium board with buildings totaling over 50,000 sq ft; confirm on DOB’s covered-buildings list.
See full Local Law 97 analysis →Facade safety — Local Law 11
The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Market read. Most recent trades (2025) cleared a median $1,024/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 2.8% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
